Kelsey Grammer and fiancée Kayte Walsh will be married on his “La Cage aux Folles” Broadway stage today by an actor who plays a drag queen in the show. A source said, “They’ll be married by Terry Lavell, who plays Mercedes. He has a license to officiate weddings.

The congregation will sit in the audience seats. Kelsey wanted to get married at the Longacre because he enjoyed being in the show and feels close to the cast. Also, it’s where he fell in love with Kayte; she was always backstage.” Following the 3 p.m. ceremony, the party will move on to The Plaza for a lavish reception and dancing to a live band.
